Reliable Pressure Valves (RPVs): Built to Protect Your Gas Quality and Your Workflow

When purity, performance, and uptime matter, even small pressure changes inside a cylinder can create big challenges. That’s where Sherwood Reliable Pressure Valves (RPVs) make the difference.

RPVs, also known as Positive Flow Valves, are engineered to maintain a small, consistent positive pressure inside the cylinder, typically 30–50 psig. This built-in safeguard keeps contaminants out, protects product integrity, and reduces the risk of costly rework or rejected cylinders.

Why Operations Are Switching to RPVs

1. Protects Against Backflow Contamination

Each RPV includes a check valve that retains positive pressure even as the cylinder nears empty. This prevents system pressure from pushing contaminants back into the cylinder, helping distributors maintain consistent gas quality across every fill.

2. Eliminates Atmospheric Contamination Risks

If a customer accidentally leaves a valve open on an empty cylinder, the RPV prevents outside air, moisture, or particulates from entering. Your cylinders return cleaner, safer, and ready for processing.

3. Reduces Cleaning, Extends Cylinder Life

By minimizing contamination, RPVs help reduce the time and cost associated with internal cleaning or remediation. It’s a small upgrade that drives long-term operational efficiency.

4. Designed for High Pressure Applications

Built from durable brass and engineered for reliability, Sherwood RPVs install seamlessly into existing workflows while adding a layer of protection your team can count on.

Is Now the Right Time to Switch to RPVs?

If you're exploring ways to strengthen product purity, reduce contamination-related downtime, or build more consistency into your refill process, RPVs may be the most effective next step.
